Making a switch from 4.10's to 4.30's , trying to get some 60' back.
Have you thought of making the low gear ratio steeper? I did, went from stock 2.45 to a Mopar direct connection set of 2.77 low gear ratio, and my car really like it a lot The starting line ratio has a big effect on every part of the race
Cab...actually thought about it a few months ago when i was in the transmission with the hope of increase the SLR and keep my top end mph, according to Wallace my current SLR is 10.05. And now that i m thinking about just gearing it for the 1/8 mi and keeping at that for now, who knows maybe I'll change doing the cold months .
